Repairing reservoirs
The application of Envelon polymerics - the ‘liquid envelope’ - has extended into the realm of sealing water reservoirs and other structures prone to leakage or water incursion, providing an economic upgrade option for industrial water facilities and main town supplies - and giving structures that would previously have been condemned, a new lease of life.
Available from Dominion Plastic Industries, , Envelon allows authorities to thoroughly clean the reservoir inside and out, and then ensures it is sealed against any further form of leaking. This reduces the prospects for concrete cancer and other physical degradation and extends the life of the tank indefinitely.
Envelon is a liquid that is quickly and easily applied with a spray gun to leave no seams, butts or leaks - it needs no protective or decorative overcoat and is touch dry in 30 minutes.
Protection is provided in two ways - first Envelon coatings form tough and flexible films with very low water vapour transmission rates while stopping substrate corrosion caused by electrolytic action or by the presence of water-borne oxygen, while its thick film protects against surface damage from abrasion and chemicals.
The strength it provides is a barrier against bending, hammering, scratching or stretching. Whether the application is above ground or below ground, the Envelon coating will remain waterproof.
Envelon polymerics are fade-resistant and dirt and grime washes off their smooth surface. They are stabilised to retain colour, gloss and flexibility, even in prolonged exposure to sunlight and harsh environments.
